PLV8 is a PostgreSQL extension that adds a trusted procedural language powered by the V8 JavaScript engine, letting you write stored procedures, triggers, and functions in JavaScript callable from SQL. It provides built-ins for logging, database access via SPI, prepared plans, cursors, and automatic type mapping between JavaScript and PostgreSQL.

Use cases

• write stored procedures in javascript for postgres
• create postgres triggers using javascript
• run javascript inside postgresql queries
• use v8 engine as a postgres procedural language
• process data in postgres with javascript
• define custom postgres functions without plpgsql

When to choose

• you need JavaScript logic inside PostgreSQL as functions, triggers, or inline DO blocks
• your team prefers JavaScript over PL/pgSQL or PL/Python for database logic
• you want automatic mapping between JavaScript values and PostgreSQL types

When to avoid

• you only need simple SQL logic that PL/pgSQL handles well
• you cannot install native extensions on your managed Postgres service
• you need a sandboxed, untrusted language for public multi-tenant databases
